The vanadia-titania aerogel catalyst of the invention is an aerogel form having many porosities and a high specific surface area obtained by performing a supercritical drying of vanadia-titania wet gel, which is prepared by a sol-gel method, with carbon dioxide and then firing the dried vanadia-titania, with a micro porosity structure being maintained, consists of vanadia and titania wherein a content of the vanadia is 1˜15 wt % of an overall catalyst weight. In addition, according to the invention, the vanadia-titania aerogel catalyst may further comprise a manganese oxide of 1˜5 wt % or a sulfur component of 0.0001˜1 wt %. Since the vanadia-titania aerogle catalyst of the invention has the very high conversion rate and selectivity for the complete oxidation reaction of the chlorinated aromatic compound and is very thermally stable, it can be usefully used in the oxidation reaction having a high heating value capable of generating local heat spots.

    摘要： A method for preparing carbon aerogels and carbon aerogels obtained therefrom are disclosed. The method for preparing carbon aerogels comprises: mixing organic starting materials including phloroglucinol and furfural with a solvent capable of dissolving the organic materials in a predetermined ratio to form a sol solution; adjusting pH of the sol solution adequately by using an acidic or basic catalyst, gelling the sol solution at room temperature under atmospheric pressure, and aging the resultant gels; substituting the solvent in thus obtained gels with liquid carbon dioxide, followed by drying in a supercritical state, to form organic aerogels; and pyrolyzing the organic aerogels in an electric furnace under inert atmosphere to obtain carbon aerogels. Particularly, the gels are formed at room temperature in a short period of time by adequately adjusting pH of the sol solution. Therefore, the method provides improved time efficiency and energy efficiency as compared to existing methods for preparing gels. Additionally, the method allows supercritical drying while avoiding a need for an additional solvent substitution, thereby simplifying the overall process. Further, the method enables preparation of carbon aerogels for supercapacitors having a high specific surface area and high capacitance even in the absence of additional activation step.

    摘要： Provided is a zinc air fuel cell with enhanced cell performance, more particularly a zinc air fuel cell which includes a separator-electrode assembly including a perforated metal plate as a cathode current collector, a catalyst-coated carbon paper, a separator, a perforated metal plate as an anode current collector, and a tilted nonconductive support. Furthermore, a metal plate may be placed on the tilted nonconductive support and connected to the anode current collector in the separator-electrode assembly to enlarge the active area of the anode current collector. For the zinc air fuel cell according to the present invention, a manufacturing cost may be reduced by using a mixture of MnO2 and CeO2, which are low-priced metal oxides as catalyst materials for oxygen reduction, and by using a low-priced nylon filter, which has a micro-porous structure and shows high stability in alkaline electrolyte. According to the present invention, the performance of the zinc air fuel cell may be efficiently enhanced by using a separator-electrode assembly structure, which minimize a distance between the anode current collector and the cathode current collector, and by adding a metal plate which plays a role of an additional anode current collector on the tilted nonconductive support so as to increase the overall active area of anode current collector contacting with zinc pellets and to resultantly enhance the ionization of zinc.
